When you are speaking with a group of friends, the suddenly someone walks past, and says something that goes PERFECTLY with what you were just said.
Person 1-"That E.T. video is super weird, I don't even understand it."
Random Person walking past- "Yeah, it was really weird."
Person 2- "OMG!! That was such syncercation!"
